Unable to install pip in ubuntu?

问题

I tried to install pip several times but couldn't. This is how my terminal looks like while trying to install pip:

aman@aman-HP-Pavilion-Notebook:~$ sudo apt-get install python-pip

python-pip is already the newest version.

The program 'pip' is currently not installed. You can install it by typing:
sudo apt-get install python-pip

aman@aman-HP-Pavilion-Notebook:~$ sudo pip

sudo: pip: command not found

aman@aman-HP-Pavilion-Notebook:~$

Try with this commands:

sudo apt-get purge --auto-remove python-pip

sudo apt-get update

sudo apt-get -y install python-pip

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"

python get-pip.py

verify:

pip --help

pip -V

The issue might be package available in Ubuntu 14.04 Universe repository.

If that doesn't work, download the .deb from here:

https://packages.ubuntu.com/trusty/all/python-pip/download

and right click on the .deb and install it

回答2:

the problem is probably you have two versions of python 2 installed on your PC in different locations and pip of one of the copies of python got removed somehow. so when you try to install the pip for a copy, system says that there is a pip already installed in another location and also the /usr/local/bin folder is also missing the pip file used to installed pip.

i just solved this issue so i will try to explain it in a way so that beginners also understand it properly

copy the already installed pip file to the location where it is missing instead of installing it through commands as command will detect the already installed pip.

the solution is very simple:

run these commands in a terminal (command prompt) in Ubuntu
